Kivy Fullscreen Issues

Fri Aug 10, 2018 5:56 pm

I am experiencing a range of minor problems developing Kivy for Raspberry Pi. I understand its a known issue that it will not run in windowed mode. However, when running in Full Screen mode (which I generally want), I find that I cannot take screen shots, and I cannot see the screen over VNC. Is there a way I can tweak my display properties in either (or both) instances such that the screen will be recognized by scrot or VNC?

Kivy uses HW accelerated screen access; it bypasses the framebuffer.
RealVNC has an experimental feature with which you can see the Kivy output, but you have to enable it in RealVNC.
And there are some programs to make screenshots. E.g. https://github.com/AndrewFromMelbourne/raspi2png
